U.2 NVMe SSDs

Key takeaways

  • 1,668 listings match this collection right now.
  • U.2 drives use the same SFF-8639 connector as SAS and SATA, so a drive can seat in a bay with no NVMe lanes wired and simply not appear.
  • U.2 drives can be a 15mm z-height, thicker than the 7mm or 9.5mm of a standard drive, and a bay built for the thin size will not close around it.
  • U.2 drives built for dual-port NVMe split the four PCIe lanes into two independent x2 paths for multipath redundancy, a capability the backplane wiring has to support to use.

U.2 is the 2.5-inch hot-swap NVMe form factor, using the SFF-8639 connector that carries four PCIe lanes into a standard drive bay. A U.2 drive needs an NVMe-capable backplane; it will not work in a SAS or SATA bay of the same size.

How to choose solid state drives

Interface first: SATA drives work on a SAS backplane, SAS drives do not work on a SATA-only controller, and NVMe connects over PCIe lanes in U.2, U.3, M.2, E1.S or add-in-card form factors that are not interchangeable with each other. Then the endurance class the workload needs, stated as drive writes per day. Then whether the listing includes the hot-swap tray, which every listing name states.
